Inventor: SUZUKAWA KAZUFUMI
IPC: G06F15/78
Filed: 1993-04-15
Abstract: PURPOSE:To extend the available frequency of the PLL circuit by providing plural VCOs whose output frequency characteristic with respect to a control voltage differs and validating their output signals alternatively according to a prescribed selection control signal. CONSTITUTION:An oscillation circuit OSC applies an input clock signal CO to a phase comparator circuit PFC of the PLL circuit. A clock shaping circuit CT delays and shapes the clock signal CD from a frequency divider circuit FD1 to generate n-phase system clock signals CP1-CPn, which are fed to a microcomputer. A control voltage VC is fed in common to VCOs 1-3 via an LPF and a corresponding selection signal is fed through external terminals CM1-CM3. The terminals CM 1-3 are coupled with a power supply voltage VCC of the circuit alternatively depending on the frequency of the signals CP 1-CPn. Thus, the available frequency of the microcomputer is extended.

Abstract: PURPOSE:To prevent deterioration in the quality of a color cathode-ray tube caused by irregularity, deviation and mixing and the like in color by providing a driver for making a linear light source move in an elliptical form long in radial direction perpendicular to the longitudinal direction. CONSTITUTION:The elliptical exposure by a linear light source 5 of an exposing device 5 itself and the elliptical exposure by the elliptical motion of the source 5 are perpendicular to each other and overlap concentrically when the source 5 is moved in an elliptical form. The exposure for the sensitive film 12 of a face panel 11 can therefore be corrected to circular shape close to a true circle. As a result, luminescent face patterns comprising plural three-colored luminescent points can always be formed accurately. It is thus possible to prevent degrading in the quality of a color cathode-ray tube caused by irregularity, deviation, mixing end the like in color.
